IMPROVEMENT III WINDLAss-GRANK POWER.

TO ALL WHOM IT MAY CONCERN Be it known that I, J, H. FLEMMING, of Grotontownship, in the county of Erie, and State of Ohio, have inventedcertain new and useful Improvements in Windlass-Crank Power ;and I dohereby declare thatl the following is a full and complete description ofthe same, reference being had to the accompanying drawings, making apart of this specification, in.which- Figure 1 is a side view of thecrank.

Figure 2is an edge view Figure 8 is an inside view.

Like letters of reference refer to like parts in the views.

A, iig. l, is the handle, one end of which terminates in a ring, B,ig.,3, enclosed in a shell, C. This handle is pivoted to a lip, D,protruding freni the side of the shell, as shw in hg. E, iig. 3, isaratchet-'wheel placed within the ring B, and whichis provided with deep,square notches F, instead of angular teeth, as in the ordinary ratchet.G is a lug fixed to the inside of the ring, and made to ilt into thenotches, as shown in the,

drawing. This lug answers-as a p'awl, by which the ratchetwheel isturned, communicating thereby motion to the Windlass or roller, aroundwhich the rope is wound for drawing up the weight, as follows: Theratchetwheel is keyed to the shaft ofthe roller, and turns the same, asthe handle is made to turn by the lug G engaging in the notches of thewheel, as shown in iig. 3, Thus the handle, wheel, and roller are movedaround together, thereby winding up the rope to which the weight isattached. 'In order to lower the weight swiftly, or for a rapidunwinding of the rope, the lug is disengaged from the ratchet-wheel, byforcing the handle back in the direction indicated by the dotted linesI, iig. 3, thus throwingthe lug back, as indicated by the dotted linesJ. The wheel being thus relieved, the roller will turn, and the ropeunwind more or less rapidly, according to the weight attached te it. Thedescent of the weight can be controlled, so as to cause it to descend atany speed, or entirely arrested at any point by forcing upward thehandle, and causing the ring B, surrounding the ratchet-wheel, to pressstrongly upon it, thereby arresting its descent by the induced friction;thus the crank becomes a brake for controlling the speed of thedescending weight; hence it is at once a crank and brake com bined,operating as either with equal facility and convenience. The weight maybe held suspended at any point in its descent or ascent, bymeans of theratchet-wheel K, fixed to theside of the shell, and a pawl convenientlyplaced as to fall upon and into the teeth,`at the time that. the lug isengaged in the wheel E; thusthe weight is securely held by the twowheels and pawls.

What I claim as my improvement, and desire to secure by Letters Patent,is-

The handle A, having a lodp or ring, B,'and lug G, and pivoted to theshell C, arranged in relation to thel ratchet E, operating with saidloop or ring, and in combination with the pawl and ratchet,substantially as and for the purpose lset forth. v
